Description

A kind of high-power LED cup light

Technical field

The utility model relates to a kind of lighting, relates in particular to a kind of high-power LED cup light.

Background technology

In today of global energy growing tension, each state all at the various energy-conserving products of positive searching, develops various new forms of energy.Especially at lighting field, LED (light emitting diode) is because its energy-saving and environmental protection, advantages such as the life-span is long, light efficiency is high, radiationless, shock resistance, and gets most of the attention.

Though LED uses as illumination and generally is expected, but these two problems of its heat dissipation problem and luminous efficiency are perplexing manufacturer and the application of LED always, especially heat dissipation problem is directly connected to a series of problems such as its brightness, light decay, stability, service life.

At present, the producer of many application facet is all thinking hard greatly for the heat dissipation problem that solves LED.Wherein, be in the led chip fluorescent lamp utility model patent of CN1407271A in patent publication No., LED is embedded in the wick column in the lampshade, luminous by the driving power driving LED in the lamp socket.Obviously this patent is not well considered the heat dissipation problem of LED, depend merely on the heat radiation that circumference louvre under the lamp socket still can't satisfy great power LED, therefore LED can only adopt the low-power type, can't adopt high-power LED, has limited the brightness and the scope of application of light fixture.

Summary of the invention

At the deficiency that above-mentioned prior art exists, it is a kind of by improving the high-power LED cup light that the Lamp cup structure improves heat radiation and heat transfer efficiency that the utility model provides.

To achieve these goals, the measure of the utility model employing is: the cup inner bottom part is provided with groove, is provided with jack in the groove, and described LED is fixed in the part or all of jack.

Be fixed with lens around described bottom of cup or the LED.

Described cup and lamp holder can adopt integrative-structure.

Described cup surface is provided with fin.

Described lamp holder is screw-type, bayonet type or pin type structure.

The pedestal of described LED is the cylindrical shape structure.

The material of described cup or pedestal is at least a in aluminium, zinc, copper, pottery, the aluminium alloy.

Described fin is cross direction profiles, vertically distribution or irregular distribution.

The bottom of described cup and the embedding of LED junction have epoxy resin or silica gel.

The cup surface that the utility model adopts is distributed with radiator structure, and LED directly adopts machinery to contact with cup, and heat conductivility is good, the heat that LED produces can effectively pass through radiator structure, dispel the heat, can slow down the light decay of LED, improved its stability and service life.

Lamp holder adopts normal structures such as screw thread, bayonet socket or pin type, can make the utility model on the basis of existing lamp socket, directly installs, and need not carry out the variation of structure, replaces easy.

Can select whether to install additional lens according to different needs.Bigger if desired range of exposures then can not installed lens, utilizes the reflector layer of rim of a cup inwall to carry out reflective getting final product; Grow the transmission of distance as needs, then can install lens additional, make light converge ejaculation.
